Cyclodextrin-derivatives and methods for the preparation thereof

ABSTRACT

The present invention relates to cyclodextrin derivatives, and methods for the preparation thereof, which cyclodextrin derivatives have at least one but no more than N-1 &#34;higher&#34; alkyl groups and at least one but no more than N-1 sulfate groups, wherein the total combined number of &#34;higher&#34; alkyl groups and sulfate groups does not exceed N, and further wherein N is the number of hydroxyl groups of the cyclodextrin from which the derivative was derived. The &#34;higher&#34; alkyl groups are lipids and, more particularly, aliphatic or aromatic carbon chains, especially linear carbon chains having a general structure of --O--C(═O)--(CH 2 ) n  --CH 3 , wherein n is between 6 and 24 and/or --OC(═O)--(CH 2 ) m  --CH═CH--(CH 2 ) m  --CH 3 , wherein m is at least 6. The sulfate groups disclosed herein are sulfate groups having the formula --OSO 3  R, wherein R may be H, Na, K, Li, NH 4  and/or other atoms/molecules that form monovalent cations. The CD derivatives are obtained in a two-step reaction wherein a cyclodextrin is contacted with acoylchloride followed by sulfonating SO 3  -complex.

The present invention relates to a novel family of cyclodextrin-derivatives and, in particular, to a novel family of cyclodextrin-derivatives having both "higher" alkyl groups and sulfate groups, which are useful for, inter alia, biopharmaceutical applications and to methods for the preparation thereof.

Cyclodextrins (CDs) are a well-known family of crystalline, nonhygroscopic molecules comprised of a chain of either six, seven or eight glucopyranose units that are joined to one another at the terminal ends thereof. Due to steric reasons, cyclodextrins form a cyclic structure of torus-shaped macrorings which have an internal axial cavity. The outer surface of these molecules is hydrophilic. The internal cavity of these molecules is of apolar nature.

Used for a variety of purposes, a particularly important use for cyclodextrins has been as a carrier for drug molecules and antigens, which may be entrapped in the internal cavity thereof.

Drawbacks with cylcodextrins include the fact that they have various physical, chemical and physiochemical properties (such as solubility) which, while being appropriate for its intended use, are not appropriate for use with other molecules and/or other uses.

To provide CDs having desired physical, chemical and physiochemical properties, various chemical and/or enzymatic modifications have been made to the CD molecule to provide CD derivatives thereof.

In such CD derivatives, at least one of the free hydroxyl groups of the CD molecule (there being three such free hydroxyl groups on each of the glucopyranose units of the CD molecule) has been modified. Such modification is made by substitution of either the hydrogen atom of the hydroxyl group or of the entire hydroxyl group itself, with one of a large variety of substituting groups. In this fashion, depending upon the number and the type of substitution(s) performed, CD derivatives may be obtained which possess certain specific physiochemical properties desired for its intended use.

Relative to the use of CD derivatives as a carrier for drug molecules and antigens, it is noted that the complexation of a drug molecule or an antigen with a CD derivative can provide significant advantages in regards to improving the bioavailability and stability of the drug molecule. In such cases, improvements in the association between the CD derivative and the drug molecule can provide concomitant improvements in the bioavailability and/or stabilization of the drug molecule.

Unfortunately, the fabrication of such CD derivatives can often prove difficult and/or involve the use of procedures which are difficult, costly and even dangerous, especially on an industrial scale.

A further problem with CD derivatives is that, like conventional CDs, they possess specific physical, chemical and physiochemical properties (such as its shape, which can effect the fitting of the guest molecule in the internal axial cavity) which, while making them suitable for specific intended purposes, limit their wider for other purposes.

Accordingly, it is obvious that there remains a need for cyclodextrin derivatives which possess physiochemical properties that permit their wider use for various purposes. It can further be seen that there remains a need for an easy, safe and inexpensive method for the preparation of such CD derivatives on an industrial scale.

It is a primary object of the present invention to provide CD derivatives which are capable of forming complexes with a wide variety of guest molecules, especially drug molecules and antigens, and which possess physiochemical properties suitable for a wide variety of purposes.

The nature and the substance of the teachings of the present invention, as well as objects and advantages thereof, will become more fully appreciated and better understood by reference to the following description when read in conjunction with the accompanying figures.

The present invention relates to our finding of a family of CD derivatives having "higher" alkyl groups and sulfate groups, and compositions thereof which have desired physiochemical properties.

The present invention further relates to our finding of a simple and easy method for safely preparing a family of CD derivatives wherein various (or all) of the hydroxyl groups (and/or portions thereof) of the CD molecule are substituted with "higher" alkyl groups and with sulfate groups, so as to provide CD derivatives having physiochemical properties that are suitable for a wide variety of uses.

Further, and as will be discussed at length below, we have found that, in using the method of the present, by either: (1) varying the quantity (ratios) of the various starting materials used; and/or (2) varying the acoylchloride(s) used; and/or (3) varying the cation(s) employed in the aqueous solution used for dialysis or ultrafiltration in practicing the method of the present invention, different compositions of CD derivatives may be produced having higher or lower quantities of (are rich in) certain CD derivatives having specific physiochemical properties which are particularly suitable for use with particular molecule(s) and/or particular use(s).

As used herein, the term "higher alkyl groups" refers to linear hydrocarbon chains of at least eight carbon atoms.

As used herein, the term "sulfate groups" refers to groups having the general formula --OSO₃ R, wherein R is selected from the group consisting of atoms and/or molecules that form monovalent cations. Examples of members of such a group are H, Na, K, Li and NH₄.

As used herein, the term "hydroxyl groups" refers to groups having the formula --OH.

The method of the present invention is usable with cyclodextrins which are comprised of either six glucopyranose units (α-cyclodextrins), seven glucopyranose units (β-cyclodextrins) and/or eight glucopyranose units (γ-cyclodextrins) for producing cyclodextrin derivatives which contain the same number of glucopyranose units.

The method of the present invention for preparing the CD derivatives of the present invention is a simple, easy and safe to perform two-step reaction, comprised of: (1) first, contacting a cyclodextrin with one or more acoylchloride to form lipidic CD (L-CD) derivatives; and (2) second, contacting the formed lipidic CD derivatives with one or more sulfonating SO₃ -complex to form the sulfo-lipidic CD (SL-CD) derivatives of the present invention.

The two steps involved in the synthesis of the CD derivatives of the present invention are considered to be ad random reactions, resulting in a collection of different CD derivatives which vary in sulphate groups and "higher" alkyl groups content and, consequently, in the structure and physiochemical properties possessed thereby.

In the first step of this process, approximately 1 mole of cyclodextrin is contacted with at least about 1 mole but no more than about N-1 moles of acoylchloride(s), wherein the total combined number of moles of acoylchloride(s) and sulfonating SO₃ -complex(es) does not exceed N, and wherein N is the total number of hydroxyl groups of the cyclodextrin contacted.

In this step, the cyclodextrin is contacted with the acoylchloride(s) for about 6 hours at approximately 60° C. If desired, the cyclodextrin can be further contacted with the acoylchloride(s) for approximately 18 additional hours at room temperature.

In the second step of this process, approximately 1 mole of cyclodextrin is contacted with from approximately 1 mole to approximately N-1 mole of sulfonating SO₃ -complex(es), wherein the total combined number of moles of acoylchloride(s) and sulfonating SO₃ -complex(es) does not exceed N, and wherein N is the total number of hydroxyl groups of the cyclodextrin contacted.

In this step, the cyclodextrin is contacted with the sulfonating SO₃ -complex(es) for at least one hour at room temperature. If desired, such contact can be for as long as (or longer than) 24 hours.

Relative to the above, it is noted that performance of the process at room temperature means that the temperature is not critical to the process. Such a feature permits the process to be performed at a wide range of temperatures and under a wide range of conditions with concommittant savings.

In this regard, it is contemplated herein that room temperatures no lower than about 10° C. would be acceptable. Preferred would be temperatures no lower than about 15° C. More preferred would be temperatures no lower than about 18° C. Most preferred would be temperatures no lower than about 22° C.

Further in this regard, room temperatures no higher than about 50° C. would be acceptable. Preferred would be temperatures no higher than about 40° C. More preferred would be temperatures no higher than about 25° C. Most preferred would be temperatures no higher than about 22° C.

The two steps of the present invention are carried out in the presence of organic solvent(s) in which the cyclodextrin from which the derivatives are made are solubilized. Preferred in this regard is a mixture of anhydrous dimethylformamide and anhydrous pyridin and/or a mixture of anhydrous N-methylpyrrolidinone and anhydrous pyridin.

The CD derivative(s) which is (are) produced by the use of the method of the present invention are removed from the organic solvents. It is preferred that such a removal of solvents from the CD derivatives includes dialyzing or ultrafiltering the CD derivatives so obtained. In this respect, it is noted that in such processes, monovalent cations may be employed. These monovalent cations are, preferably, K⁺, Li⁺, H⁺, Na⁺, and NH₄ ⁺.

It is further noted that such dialyzing or ultrafiltering may be done in the presence of a nondialyzable detergent, thereby transferring the CD derivatives from the organic solvents used for synthesis to aqueous solutions for their further use. Examples of such nondialyzable detergents are TWEEN 80 and TRITON X-100.

The CD products from which solvent has been removed may then be lyophilized if a dry CD derivative product is desired. In doing so, any lyophilization procedure, well-known to those skilled in the art, which is useful for obtaining dry products from aqueous solutions may be employed. In this respect, we note that, preferably, such lyophilization be performed at room temperature, at an internal pressure of less than 0.1 mbar and a cold trap of less than -25° C.

As noted above, in practicing the method of the present invention, the production of certains of the CD derivatives may be increased and/or decreased, as desired, by : (1) varying the quantities (ratios) of the starting materials; and/or (2) varying the types of the starting materials; and/or (3) varying the types of cation(s) in the aqueous solution used for dialysis or ultrafiltration.

Varying the quantity (ratios) of the starting materials by increasing the quantity of sulfonating SO3-complex(es) and/or by decreasing the quantity of acoylchloride(s) employed in the process of the present invention, CD derivatives having more sulfate groups relative to "higher" alkyl groups may be provided. Conversely, by decreasing the quantity of sulfonating SO₃ -complex(es) and/or by increasing the quantity of acoylchloride(s) employed in the process of the present invention, CD derivatives having more "higher" alkyl groups relative to sulfate groups may be provided.

For illustration of this point, using five moles of sulfonating SO₃ -complex (such as chlorosulphonic acid) and 3 moles of acoylchloride (such as lauroylchloride) will provide a composition which is rich in CD derivatives having 5 sulfate groups and 3 "higher" alkyl groups. Similarily, using 5 moles of sulfonating SO₃ -complex (such as chlorosulphonic acid) and 11 moles acoylchloride (such as lauroylchloride) will provide a composition rich in CD derivatives having 5 sulfate groups and 11 "higher" alkyl groups.

Varying the acoylchloride(s) employed in the process of the present invention, provides CD derivatives having different "higher" alkyl groups possessing specific desired physiochemical properties which are particularly suitable for use with particular molecule(s) and/or particular use(s). For example, octanoylchloride will yield alkyl groups of the formula --OC(═O)--(CH₂)₆ --CH₃, decanoylchloride will yield alkyl groups of the formula --OC(═O)--(CH₂)₈ --CH₃, dodecanoylchloride will yield alkyl groups having the formula --OC(═O)--(CH₂)₁₀ CH₃, tetradecanoylchloride will yield alkyl groups having the formula --OC(═O)--(CH₂)₁₂ --CH₃, hexadecanoylchloride will yield alkyl groups having the formula --OC(═O)--(CH₂)₁₄ --CH₃ and octadecanoylchloride will yield alkyl groups having the formula --OC(═O)--(CH₂)₁₆ --CH₃ or --OC(═O)--(CH₂)₇ --CH═CH--(CH₂)₇ --CH₃.

Varying the type of cation(s) employed in the aqueous solution used for dialysis or ultrafiltration in the process of the present invention by using H⁺, K⁺, Na⁺, NH₄ ⁺ and/or Li⁺, provides CD derivatives having different sulfate groups (--OSO₃ H, --OSO₃ K, --OSO₃ Na, --OSO₃ NH₄ and --OSO₃ Li, respectively)--possessing specific desired physiochemical properties which are particularly suitable for use with particular molecule(s) and/or particular use(s).

In the above fashion, the production of certain CD derivatives may be increased/decreased as desired, so that the composition obtained thereby contains higher or lower quantities of (is rich in) certain CD derivatives having specific physiochemical properties which are particularly suitable for use with particular molecule(s) and/or particular use(s).

This is based upon our finding, which will be discussed at length below, that the physiochemical properties of the CD derivatives prepared according to the method of the present invention depends on the ratio of the sulfate groups, "higher" alkyl groups and hydroxyl groups present, the type of counter-ion of the sulphate groups, and the type of "higher" alkyl groups of the CD derivative. The hydrophobic character of the "higher" alkyl group is of particular note in this regard.

Physiochemical properties of the CD derivatives of the present invention which may be so adjusted include, among others, solubility in aqueous (water) and nonaqueous (apolar) solvents, the capacity to form micelles and mixed micelles with other compounds, the capacity to adsorb to hydrophobic surfaces and surface-activity/tenso-activity.

The production of compositions rich in CD derivatives of higher (or increased) water solubility may be increased by:

The production of compositions rich in CD derivatives of higher (or increased) solubility in apolar solvents (such as chloroform, methyl tert-butyl ether, dichloromethane, hexadecane and mineral oil) may be increased by:

(1) decreasing the quantity of sulfonating SO₃ -complex(es) employed in the method of the present invention and/or by increasing the quantity of acoylchloride(s) employed in the method of the present invention; and/or

(2) employing dodecanoylchloride (lauroylchloride), tetradecanoylchloride (myristoylchloride) hexadecanoylchloride (palmitoylchloride) and/or octadecanoylchloride (stearoylchloride and oleoylchloride), as the acoylchloride reagent(s); and/or

(3) employing K⁺ and/or Na⁺ as the counter-ion for the sulfate groups in either dialysis and/or ultrafiltration, which provides the CD derivative produced thereby with the sulfate groups --OSO₃ K and --OSO₃ Na, respectively.

The production of compositions rich in CD derivatives which have a higher (or increased) capacity to form micelles may be provided by increasing the quantity of sulfonating SO₃ -complex(es) employed in the method of the present invention and by increasing the quantity of acoylchloride(s).

Conversely, the production of compositions which are rich in CD derivatives which have a lower (or decreased) capacity to form micelles may be provided by decreasing the quantity of sulfonating SO₃ -complex(es) employed in the method of the present invention and by decreasing the quantity of acoylchloride(s).

The production of compositions which are rich in CD derivatives having a higher (or increased) surface activity/tensio-activity may be provided by increasing the quantity of both the sulfonating SO₃ -complex(es) used and the quantity of acoylchloride(s) employed in the process of the present invention.

Conversely, the production of compositions which are rich in CD derivatives having a lower (or decreased) surface activity/tensio-activity may be provided by decreasing the quantity of both the sulfonating SO₃ -complex(es) employed and the quantity of acoylchloride(s) employed in the process of the present invention.

The physicochemical properties of the CD derivatives of the present invention depends on the number (and ratio) of sulfate groups and (to) "higher" alkyl groups (and to a lesser extent the number of hydroxyl groups) which are present as well as the nature of the counter-ion of the sulfate groups and the type and nature of the "higher" alkyl groups.

The novel cyclodextrin derivatives of this composition have both sulfate groups and "higher" alkyl groups (and, if desired, hydroxyl groups) that are covalently-linked to the CD molecule.

Further CD derivatives disclosed herein have no more than N-7 such sulfate groups, wherein N is the total number of hydroxyl groups of the cyclodextrin from which the derivative was obtained. Still further CD derivatives disclosed herein have no more than seven such sulfate groups.

In another aspect of the present invention, CD derivatives are provided having ratios of sulfate groups to "higher" alkyl groups which provide the CD derivative with physiochemical properties that are specifically suited (optimized) for a particular intended purpose or use.

In this regard, many different CD derivatives of the present invention have been synthesized according to the methods of the present invention, to provide CD derivatives which have specific physiochemical properties. Depending upon the profile of the pharmaceutical form and physiochemical and biological properties of the drug molecule complexed therewith and carried thereby, different CD derivatives demonstrate distinct efficacy with potential advantages in certain cases.

CD derivatives are provided herein having physiochemical properties such as, among others, solubility in aqueous and nonaqueous solvents, the capacity to form micelles, the capacity to form mixed micelles with other compounds, the capacity to adsorb to hydrophobic surfaces and specific surface-activity/tenso-activity.

In particular, CD derivatives having increased water solubility are provided wherein the ratio of sulfate groups present to "higher" alkyl groups present is increased. This can also be achieved by, for example, the sulfate groups being --OSO₃ H and --OSO₃ NH₄ and/or the "higher" alkyl groups being --OC(═O)--(CH₂)_(n) CH₃, wherein n is 6-12, as was discussed at length above.

Conversely, CD derivatives having decreased water solubility are provided as the ratio of sulfate groups present to "higher" alkyl groups present is decreased. This can also be achieved by, for example, the sulfate groups being --OSO₃ K and --OSO₃ Na and/or the "higher" alkyl groups being --OC(═O)--(CH₂)_(n) CH₃, wherein n is 12-18 and/or --OC(═O)--(CH₂)_(m) --CH═CH--(CH₂)_(m) --CH₃, wherein m is at least 6, as was discussed at length above.

To illustrate the point involving ratios, the following examples are cited CD derivatives which have 2 sulfate groups and 10 "higher" alkyl groups are more water soluble than CD derivatives having 2 sulfate groups and 11 or more "higher" alkyl groups, but are less water soluble than CD derivatives having 2 sulfate groups and 9 or less "higher" alkyl gropus. Similarily, CD derivatives having 2 sulfate groups and 10 "higher" alkyl groups will be more water soluble than CD derivatives having 1 sulfate group and 10 "higher" alkyl groups but less water soluble than CD derivatives having 3 sulfate groups and 10 "higher" alkyl groups.

CD derivatives having increased solubility in apolar solvents (such as chloroform, methyl tert-butyl ether, dichloromethane, hexadecane and mineral oil) are provided as the ratio of sulfate groups present to "higher" alkyl groups present is increased. This can also be achieved by, for example, the sulfate groups being --OSO₃ H and --OSO₃ NH₄ and/or the "higher" alkyl groups being --OC(═O)--(CH₂)_(n) CH₃, wherein n is 12-18 and/or --OC(═O)--(CH₂)_(m) --CH═CH--(CH₂)_(m) --CH₃, wherein m is at least 6, as was discussed at length above.

Conversely, CD derivatives having a decreased solubility in apolar solvents are provided as the ratio of sulfate groups present to "higher" alkyl groups present is increased. This can also be achieved by, for example, the sulfate groups being --OSO₃ K and --OSO₃ Na and/or the "higher" alkyl groups being --OC(═O)--(CH₂)_(n) CH₃, wherein n is 6-12, as was discussed at length above.

CD derivatives having an increased capacity to form micelles are provided as the the number of sulfate groups present and the number of hydrophobic (i.e., "higher" alkyl) groups present is increased.

Conversely, CD derivatives having a decreased capacity to form micelles are provided as the number sulfate groups present and the number of hydrophobic (i.e., "higher" alkyl) groups present is decreased.

In the above regard, the CD derivatives of the present invention can form large mixed micelles with other compounds. For example, a CD derivative with a sulfate/lauroyl ratio of 1.4 sulfate groups to 7.7 lauroyl groups per CD dervative molecule forms large mixed micelles with TWEEN 80 (MERCK) which do not pass ultrafiltration membranes with a cut-off as high as 100,000 daltons. The size of the mixed micelles with other compounds depends on the ratio of the hydrophilic (i.e., sulfate) groups and hydrophobic (i.e., "higher" alkyl) groups, on the hydrophobicity of the hydrophobic groups and on the physiochemical features of the molecule to be associated therewith.

CD derivatives having an increased surface activity/tensio-activity are provided as the total number of sulfate groups present is increased and/or the total number of hydrophobic (i.e., "higher" alkyl) groups present is increased and/or as the total number of sulfate groups present and "higher" alkyl groups present is increased.

CD derivatives having a decreased surface activity/tensio-activity are provided as the total number of sulfate groups is decreased and/or the total number of hydrophobic (i.e., "higher" alkyl) groups present is decreased and/or as the total number of sulfate groups present and "higher" alkyl groups present is decreased.

In illustration of the above, CD derivatives of the present invention can bind to hydrophobic surfaces (for example, the CD derivatives of the present invention with a ratio (per CD derivative) of sulfate groups to lauroyl groups of 1.4 sulfate groups to 7.7 lauroyl groups per CD derivative molecule binds to droplets of a squalane-in-water emulsion.

CD derivatives having an increased capacity to bind to hydrophobic surfaces are provided by the "higher" alkyl groups being provided by the "higher" alkyl groups being --OC(═O)--(CH₂)_(n) CH₃, wherein n is 12-18 and/or --OC(═O)--(CH₂)_(m) --CH═CH--(CH₂)_(m) --CH₃, wherein m is at least 6, as was discussed at length above.

Conversely, CD derivatives having a decreased capacity to bind to hydrophobic surfaces are provided the "higher" alkyl groups being --OC(═O)--(CH₂)_(n) CH₃, wherein n is 6-12, as was discussed at length above.

By using the methods of the present invention, compositions of novel cyclodextrin derivatives may be provided which may be used as such, without being separated from the other CD derivatives which are produced and which are present therewith.

However, if desired and/or necessary, certain(s) of the CD derivative(s) which is (are) produced by the use of the method of the present invention may then be separated and purified from the remainder of the CD derivatives produced for subsequent use thereof, by the use of classical methods well-known in the art, such as ion-exchange chromatography, reverse-phase chromatography, crystallization from solutions, etc.

The CD derivatives disclosed herein, when complexed with a molecule (such as a drug molecule or antigen), provides improved bioavailability of the molecule from solid and/or semisolid and/or liquid formulations. They also provide enhanced stability and improved shelf-life. Further, they reduced the side effects (toxicity) of the guest molecule carried thereby. Finally, they make possible the provision of uniform easy-to-handle powders (even from liquids) and aqueous injectable solutions (from poorly-soluble drugs).

The novel CD derivatives of the present invention may be used for those same purposes which CDs and other CD derivatives are presently and conventionally employed. In particular, it is contemplated herein that the CD derivatives of the present invention may be used for medical purposes as a carrier for drug molecules and antigens.

In this regard, the CD derivatives of the present invention may, using protocols and under conditions which are well-known to those skilled in the art, be complexed with drug molecules and/or antigens (which are also well-known to those skilled in the art for medical uses) to produce therapeutic and/or prophylactic compositions, such as vaccines and other therapeutic and/or prophylatic compositions, which may then be used as such for medical purposes.

An example of such a medical use is the use of the CD derivatives (and compositions thereof) in adjuvants. Suitable adjuvants include those commonly referred to as oil-in-water (including squalane-in-water, mineral oil-in-water and soya oil-in-water) emulsions.

Having described the preferred embodiments of the CD derivatives of the present invention and the methods for the production thereof, reference is now made to the following examples which are meant herein to be illustrative only.

EXAMPLE 1

For the synthesis of the cyclodextrins of the present invention, as described in this and the following examples, the utmost precautions were taken to avoid contacting the different starting materials with water.

Water was removed from 4 gram samples of β-CD (ACROS) by heating of the 4 gram samples for 4 hours at 120° C.

Water was removed from a 1:1 (v/v) mixture of anhydrous dimethylformamide (JANSSEN CHEMICA) and anhydrous pyridin (JANSSEN CHEMICA) by adding thereto molecular sieves (2A by MERCK, Darmstadt Germany) and incubating the mixture in a closed container for at least 48 hours at room temperature. The anhydrous dimethylformamide/pyridin mixture was then separated from the molecular sieves by decanting the anhydrous mixture into a dry container.

Respective 4 gram samples of the dried CD was then solubilized in respective 50 ml samples of the anhydrous dimethylformamide/pyridin mixture.

Lauroylchloride (MERCK, GERMANY) was then added to the respective solubilized CD samples in the quantities set forth below in Table 1 and the reaction mixtures incubated for six hours at 60° C., followed by incubation for 18 hours at temperatures of between 15 and 22° C. (room temperature). In this manner, L-CD solutions were obtained.

Chlorosulphonic acid (MERCK, GERMANY), in the quantities set forth below in Table 1, were added to respective samples of the anhydrous dimethylformamide/pyridin mixture which was prepared as described above. These respective mixtures were then added to respective L-CD solutions, as is also set forth in Table 1. The reaction mixtures thus obtained were then incubated for 24 hours at a temperature of between 15 and 22° C. (room temperature).

Following incubation, solvents were then partially removed from the reaction mixtures by evaporation at low pressure (200 millibars) for 1-2 hours at 60° C. Solvents were further removed by extensive dialysis using a membrane of regenerated cellulose with a cut-off of between 1,000 and 10,000 daltons (SPECTRA/POR) against isotonic phosphate buffered saline (PBS comprised of, per liter of water: 8 g sodium chloride, 0.2 g potassium chloride and 1.15 g disodium hydrogen phosphate having a pH of 7.3) and subsequently against ultrapure water until no solvent was detected in the filtrate. The volume ratio of dialysate (PBS or ultrapure water) and the residue used in the dialysis was maintained at >10:1 (v/v). The dialysis procedure was conducted for at least 10 days with the dialysate being replaced at least once a day. Dry products were obtained by lyophilization of the residue at room temperature, an internal pressure of less than 0.1 mbar and a cold trap of at less than -25° C.

The chemical compositions of the CD derivatives obtained were then determined by measuring the cyclodextrin content, the bound sulphate content, the total lipid content, the free lipid content and the bound lipid content (calculated by subtracting the free lipid content from the total lipid content), as described in Hilgers et al., VACCINE 12, 653-660 (1994).

The composition of the CD derivatives were expressed as the mean number of bound sulphate groups per molecule of the cyclodextrin derivatives produced and the mean number of bound lipid groups per molecule of the cyclodextrin derivatives produced.

The composition of the mean numbers of bound sulphate groups and bound lipid groups per molecule of the cyclodextrin derivatives produced are summarized in Table 1.

EXAMPLE 5

Water was removed from 310 gram samples of β-CD (ACROS) by heating of the 310 gram samples for 4 hours at 120° C., yielding approximately 280 grams of dried CD.

Water was removed from a 5:2 (v/v) mixture of anhydrous N-methylpyrrolidinone (5 parts) and anhydrous pyridin (2 parts) by adding thereto molecular sieves (2A by MERCK, Darmstadt Germany) and incubating the mixture in a closed container for at least 48 hours at room temperature. The anhydrous N-methylpyrrolidinone/pyridin mixture was then separated from the molecular sieves by decanting the anhydrous mixture into a dry container.

Respective 280 gram samples of the dried CD was then solubilized in respective 2000 ml samples of the anhydrous N-methylpyrrolidinone/pyridin mixture.

Lauroylchloride was then added to the respective solubilized CD samples in the quantities set forth below in Table 33 and the reaction mixtures incubated for six hours at 60° C., followed by incubation for 18 hours at temperatures of between 15 and 22° C. (room temperature). In this manner, L-CD solutions are obtained.

Chlorosulphonic acid, in the quantities set forth below in Table 33, were added to respective samples of the anhydrous N-methylpyrrolidinone/pyridin mixture which was prepared as described above. These respective mixtures were then added to respective L-CD solutions, as is also set forth in Table 33. The reaction mixtures thus obtained were then incubated for 24 hours at a temperature of between 15 and 22° C. (room temperature).

Following incubation, solvents were then removed from the reaction mixtures by addition thereto of (per gram CD in the reaction mixture) both 5 grams TWEEN 80 (ICI) and 5 grams ultrapure water. Then two parts (v/v) ultrapure water was added to the respective mixtures and the mixtures subsequently ultrafiltered over an ultrafiltration membrane of regenerated cellulose with a 10 kD (kilodalton) cut-off (HOECHST) until the original volume was recovered.

The procedure of adding two parts (v/v) of ultrapure water to the recovered residue followed by ultrafiltration was then repeated twelve times to ensure that the solvent concentration was within an acceptable level.

In this manner, aqueous solutions of the CD derivatives plus TWEEN 80 in ultrapure water were obtained.

The chemical compositions of the CD derivatives obtained were then determined as described at length above in Example 1 and are herebelow summarized in Table 33:

EXAMPLE 6

A 4.5 gram sample of β-cyclodextrin (ACROS) was solubilized in a 100 ml 1:1 (v/v) mixture of anhydrous dimethylformamide (JANSSEN CHEMICA) and anhydrous pyridin (JANSSEN CHEMICA) water was then removed from the solution by adding thereto molecular sieves (2A by MERCK, Darmstadt Germany) and incubating the mixture in a closed container for at least 48 hours at room temperature. The anhydrous mixture was then separated from the molecular sieves by decanting the anhydrous mixture into a dry container.

6.6 grams of Lauroylchloride (MERCK, GERMANY) was then added to the solubilized CD sample and the reaction mixtures incubated for six hours at 60° C., followed by incubation for 18 hours at temperatures of between 15 and 22° C. (room temperature). In this manner, L-CD solutions were obtained. 0.6 grams of Chlorosulphonic acid (MERCK, GERMANY) was then added to 10 ml sample of the anhydrous dimethylformamide/pyridin mixture which was prepared as described above in Example 1. This mixture was then added to the L-CD solution. The reaction mixture thus obtained was then incubated for 24 hours at a temperature of between 15 and 22° C. (room temperature).

Following incubation, solvents were then partially removed from the reaction mixtures by evaporation at low pressure (200 millibars) for 1-2 hours at 60° C. Solvents were further removed by extensive dialysis using a membrane of regenerated cellulose with a cut-off of 10,000 daltons (SPECTRA/POR) against isotonic phosphate buffered saline (whose composition is discussed at length above in Example 1) and subsequently against ultrapure water until no solvent was detected in the filtrate. The volume ratio of dialysate (PBS or ultrapure water) and the residue used in the dialysis was maintained at >10:1 (v/v). The dialysis procedure was conducted for at least 10 days with the dialysate being replaced at least once a day. Dry products were obtained by lyophilization of the residue at room temperature, an internal pressure of less than 0.1 mbar and a cold trap of at less than -25° C.

The chemical compositions of the CD derivatives obtained were then determined by measuring the cyclodextrin content, the bound sulphate content, the total lipid content, the free lipid content and the bound lipid content (calculated by subtracting the free lipid content from the total lipid content), as described by Hilgers, et al., VACCINE 12, at pages 653-660 (1994).

The composition of the CD derivatives were expressed as the mean number of bound sulphate groups per molecule of the cyclodextrin derivatives produced and the mean number of bound lipid groups per molecule of the cyclodextrin derivatives produced. In this regard, the calculated mean number of bound lipid groups was determined to be 7.35 bound lipid groups/CD molecule and the calculated mean number of bound sulphate groups was determined to be 1.4 bound sulphate groups/CD molecule.

A 1% (w/v) solution of the SL-CD derivatives was prepared by dissolving about 1 gram of the CD derivatives obtained in a minimal volume of about 20 ml of methyl tert-butyl ether (MERCK), adding (per gram of the CD derivative added) 2 ml of the TWEEN 80 and evaporating the tertmethyl-butyl ether at an elevated temperature (about 60° C.) and reduced pressure (80 millibar) until a viscuous solution of the SL-CD derivative in the TWEEN 80 has been obtained.

10 ml of water per gram of the SL-CD derivative was slowly added. Thereafter, the appropriate volumes of PBS and either squalane (ALDRICH) or soya oil or hexadecane (SIGMA) were added to respective samples. The mixture was emulsified with a microfluidizer (MICROFLUIDICS Corp., USA) until no drops of oil larger than 2 or 3 μm were visible under the microscope (magnitude 1000). The emulsions containing, per ml, 10 mg SL-CD, 20 mg TWEEN 80 and 80 mg of either squalane, soya oil or hexadecane, were then stored at 4° C. until use.

The vaccines were prepared by mixing one volume of antigen with one volume of adjuvant. The antigens were prepared such as is described in Vaccine 12, p. 653-660 and Vaccine 12, p. 661-665 (1994). Two solutions of different antigens were used: solution I which included, per ml: 10 μg of inactivated influenza virus MRC-11 (SOLVAY DUPHAR) and 1000 μg OVA (SIGMA); and solution II which included, per ml: 4.4 μg/ml of inactivated influenza virus, strain A/swine (SOLVAY DUPHAR), 4.0 μg of inactivated influenza virus, strain MRC-11 (SOLVAY DUPHAR), 2.0 μg of inactivated influenza virus, strain X-79 (SOLVAY DUPHAR) and 10⁸ TCID₅₀ of inactivated pseudorabies virus (SOLVAY DUPHAR).

8-10 week old NMRI female mice (CHARLES RIVER, GERMANY), each weighing about 20 grams, were immunized by injection in the foot pad with 0.025 ml of vaccine and the antibody titres were measured three weeks later

The antibody titres were expressed by geometric means (² log±SEM). The analysis of the antibody titres was effectuated by standardized tests using criteria for their validity as were described previously in Vaccine 12, p. 653-660 (1994).

The Student's t test was performed to analyze the statistical significance of the results and a P<0.05 was considered as significant.

The adjuvant formulations were tested in mice in two independent experiments.

The results of these experiments are summarized below in Table 37:

All SL-CD derivative/oil/water emulsions increase the humoral response against influenza virus, strain MRC-11 and against OVA.

EXAMPLE 7

Swine specimens, 8 to 10 weeks of age have been tested for the eventual presence of antibodies against the viral antigens in questions and the specimens with detectable antibody titres have been excluded.

The SL-CD derivatives of the present invention were synthesized as described above in example 6.

A mineral oil-in-water emulsion sold under the name SUVAXYN O/W EMULSION (SOLVAY DUPHAR) was then obtained and formulations of SL-CD derivatives in an emulsion of squalane-in-water were prepared as described above in Example 6.

Vaccines containing the adjuvant formulations were also prepared as described above in Example 6.

The formulations of SL-CD derivatives-in-squalane-in-water, of mineral oil-in-water and of no adjuvant were then tested for their adjuvant effect on swine specimens having inactivated pseudorabies virus and inactivated influenza virus strains MRC-11 and A/Swine as antigens. The animals were immunized two times (week 0 and week 3) and the antibody titres measured three weeks (week 6) after the second injection.

The results of these experiments are summarized below in Table 38:

The antibody titres against PRV (anti-PRV) were augmented by use of emulsions of SL-CD derivatives-in-squalane-in-water (SL-CD/squalane/water). The antibody titres measured were comparable to or more elevated than those obtained by the mineral oil-in-water emulsions used in commercial products. The antibody response against A/swine and against MRC-11 were also been augmented by the formulations of SL-CD-derivatives-in-squalane-in-water (SL-CD/S/W) and mineral oil-in-water.

EXAMPLE 8

Other than the adjuvant effect, other properties are important for the evaluation of a vaccine. Among others, a local reaction is an important aspect as well as a certain reaction at the site of injection being accepted in general in certain species of animals. The local toxicity has been tested in vivo following the swelling of the mouse pads after injection of the vaccine. It showed that this method is very sensitive.

The SL-CD derivatives of the present invention were synthesized as described above in Example 6.

Formulations of SL-CD derivatives in oil-in-water emulsions of squalane-in-water, of soya oil-in-water and of hexadecane-in-water were prepared as described above in Example 6.

Vaccines containing the adjuvant formulations were also prepared as described above in Example 6.

Groups of six mice were treated with 25 μl of vaccine per subcutaneous injection in the pad of the rear left foot. The vaccine included one volume of antigen solution containing 10 μg of MRC-11 and 1 mg of ovalbumine (OVA) per ml of PBS and one volume of adjuvant.

The thickness of the pads was measured one day before and at several intervals after the injection by an semi-electronic device specially developed for this purpose by the University of Utrecht (UTRECHT, Netherlands). The precision of this apparatus is about 0.02 mm.

The swelling was calculated by substracting the thickness of the pad before the treatment and the thickness of the pad after the treatment, such thickness being expressed in 0.01 mm.

The results are summarized below in Tables 39 and 40:

From the above Tables, the reactogenicity of SL-CD included in the different oils has been very weak or absent. The emulsions containing SL-cyclodextrin in squalane and hexadecane provoked some swelling for one or two days after the injection, whereas the SL-cyclodextrin in soya oil did not provoke a visible response.

The reactogenicity, that is to say, the local toxicity tested on mice show pronounced effects in function of the type of oil.

EXAMPLE 9

The SL-CD derivatives of the present invention were synthesized as described above in Example 6.

Formulations of SL-CD derivatives in oil-in-water emulsions of squalane-in-water, of soya oil-in-water and of hexadecane-in-water were prepared as described above in Example 6.

The stability of the emulsions was tested in vitro by exposing the formulations to an elevated temperature during a fixed period of time. In general, emulsions are less stable at high temperatures and the test at elevated temperatures was considered as giving indications on the behavior on long term at lower temperatures.

The stability of the emulsions was determined at 37° C. Sterile aliquots of 5 ml of emulsion comprising 0.01 % (w/v) of thimersol (SIGMA), were incubated at 37° C. and the formation of oil drops, the appearance of an oil phase and other modifications have been verified each day by inspection of the emulsions with the naked eye.

The results are summarized below in Table 41:
